  • RAW MATERIALS IN CEMENT PRODUCTION

    The choice of composition of materials mixture with useful components generally is determined by plant’s geographical location and delivery of raw materials. The only common feature in all cement production plants is the difficulty of grinding the source material as the material is hard enough and has high abrasiveness.cement manufacturing,Material is fed from inlet and ground materials discharged through the other end of the ball mill. For drying the material, hot air is introduced to remove moisture in the raw material. Grinding can be in two ways viz. closed circuit and open circuit grinding. In open circuit grinding, passage of material is only once through the mill.
